IMPROVEMENT IN BRICK-PRESSES. I

'nescheeule referred te in the Letters Paten; and making pm of the name.

To all whom it may concern Be it known that I, J AMES RCLARK, ofMorenci, in the county of Lenawee and State of Michigan, have invented anew and valuable Improvement in Brick- Presses; and I do hereby declarethat the following isa full, clear, and exact description oftheconstruction and operation of the same, reference being hadto theannexed drawing making a part of this specification', and to the lettersand.figu1 'es-of 'reference marked thereon. l

l Figure 1 of the drawing is a representation of my brick-press in planview, and

Figure 2 lis a longitudinal vertical section of the same. f

The nature ofmy invention consists inthe construction and arrangement ofabrick-press for pressing the bricks after they have been molded andpartly dried iny the yard; and

To'enable others skilled iu the art to which my in-` vention appertainsto make and use the same, `Il will now proceed to describe itsconstruction and operation.

A represents the bediof my machine, at a suitable Y point on which aretwo posts or standards, B B.

Between the upper ends of these posts is pivoted the hand-lever C, bymeans of' which the press is operated.

From the lever G, on each side,a bara, extends down to a. ltoggle-joint,b, in the center of a lever, D,

f which, at one end, is pivoted orbinged to the end of the bed A, thenpassing between the p'osts B B the other end of said lever is hingedorpivoted to a plunger-rod or beam This rod or beam E, which, at its otherend, is provided with the plunger' G, moves horizontally between twoguidelblocks, H H, placed on the bed A, said blocks biengprovided withlips or tongues on their inner sides, which project into grooves in thesides of the beam.

, Whenthe jointed lever D is pressed down on the Y bed A, the plunger Gjust enters the mouth of a box, I, of the size of one brick, placed onthe other end ot' the bed.

In addition to its stationary back, the box I is provided with a movableback, J, which is operated by a bent rod, e, connected with ap'ost,dcxtending from the beam-E through a longitudinal slot in the bedA, as shown in Iig. 2. i

It'will thus be seen that the plunger G being moved back and forth bymeans of the levers C D, the movable back J moves also in the samedirection, but the plunger m'oves a trille farther, or else the brickwould not be pressed. lhis is accomplished by passing the rod e throughthe post 'cl loosely, and inserting a pin, t, through the rod e on eachside aud a short distance from the post. It will-then be understoodthat, it' a partially-dried brick is inserted between the plunger G andthe back J, and then moved into the box I, the back J will stop whiletheplunger hns yet a short distance to move, and it is just then that thebrick is pressed.

Having thus fully described my invention, What I claim asnew, and desiretosecure by Letters Patent, is-

Y 1. Thegrooved beam E and plunger G, moving between the guides H H, andoperating in combination with the post d, rod e, pins 'i i, movable backJ and box I, substantially as and for the purposes herein set forth.

2. The combination of the bed A, posts B B,- levers C D, joint b, beamE, Aplunger G, guides H H, box I, and movable backv J, all constructedand arranged to ope-rate substantially as and for the purposes hereinset forth. v

In testimony that I claim the above, -I have nere-4 unto subscribed myname in the presence ot' two witnesses. Witnesses:

JAMES 1r. CLARK.
